Abstract:
An operational amplifier circuit structure is provided. The operational amplifier circuit structure includes a first current mirror associated with a first current mirror ratio, a second current mirror coupled to the first current mirror and associated with a second current mirror ratio, an input portion coupled to the first current mirror and the second current mirror, an output portion coupled between the input portion and the first current mirror and the input portion and the second current mirror, and associated with a first output impedance and a second output impedance, respectively, and a current source coupled to the input portion.
